The veins in the leg carry low-oxygen blood laden with wastes and carbon dioxide back to the heart just as do other veins in the body. However, the leg veins are a bit different in structure from veins elsewhere in the body. This is due to the fact that the blood has to return back to the heart against the force of gravity >> Read More ...

Arteries have thicker walls than blood vessels which is muscular and elastic. The muscles allows >> Read More ...
Congestive heart failure (CHF) or congestive cardiac failure (CCF) affects about 5 million individuals in the United States and accounts for more than half a million deaths a year.

A heart attack (myocardial infarction) is death of a portion of the muscular heart wall as a result of severely reduced blood supply. It is most commonly due to a blockage in the coronary artery which supplies oxygen-rich blood to the heart wall. An occlusion that causes injury but not death to the heart wall over a period >> Read More ...
Angina pectoris is the most common type of ischemic heart disease. Decreased blood flow to the heart muscle, usually at times of increased cardiac demand, elicits pain that is relieved upon rest or with the use of nitrates. The blood supply to the heart is compromised, most often due to coronary artery disease. Increase in >> Read More ...
